To all whom it may concern Be it known that I PAUL ORIPPEN, of Bronson, in the county ofBranch and State ofMichigan, have invented a new and Improved Wa- 5 ter-Proof Compound, of which the following is a specification.

The object of my invention is to provide a new and improved water-proof compound for coating roofs, tanks, &c., to prevent them from rusting and leaking.

My composition consists in the following ingredients, combined in the proportions stated herewith: coal-tar, six(6) parts; sulphur, three (3) parts; alum, one (1) part. These ingredients are to be thoroughly mixed by stirring and are to be boiled down about ten per cent. of their volume.

The above-named composition is to be used to cover metal and wooden roofs and car-roofs, 20 to preserve them and make them water-proof.

It is also to be used to cover timber construe:

(Specimens) tions-such as docks, piers, caissons, floatingdocks, &c.to save them from decay and to protect them from Worms. For the same purpose it is to be used to cover the lower ends of fence-posts, telegraph-poles, railway-sleepers, sills, and basement beams. It is further to be used to cover metal or wood wherever the same is to be protected from the action of the air, moisture, or worms and insects.- It is also a very good paint for making cloth and fabrics water-proof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A paint compound consisting of alum, coaltar, and sulphur boiled together, in the proportions specified.
